Lightning has sparked a few new small fires in the drought-stricken Southwest. But the thunderstorms brought welcome rain Monday to the monster blaze that’s been churning for a month in New Mexico. It’s now the largest in the state’s recorded history. The fire east of Santa Fe and south of Taos has destroyed at least 260 homes and burned an area about one-quarter the size of Delaware.

Officials at another big fire west of Santa Fe are preparing to relax evacuation orders around the Los Alamos National Laboratory.
